kconfig: add more S_INT and S_HEX consistency checks

This patch add more number consistency checkg, trying to catch the following
situation:

config FOO0
	hex
	default 42

config FOO1
	string

config BAR0
	int
	default FOO1

config BAR1
	hex
	default FOO1

config FOO2
	hex
	default 42h

config FOO3
	int
	default "1bar"
